Love this walker! My little girl is 7 months old and was pulling herself up to stand before we received the walker. She loves standing up on the walker and playing with the board. A 12-month-old little boy comes over every day and the two of them constantly "fight" over who gets to play with it. They used to get bored with their toys after only an hour or so, but now they play for hours! One of the best purchases.
Our 7-month-old has fallen, but we attribute that more to her taking her hands off the walker and trying to stand without support than to the walker itself. She is learning and growing! The little 12-month-old boy has not fallen with this. He is now walking on his own so he typically doesn't use the walker to actually move. Just to play with all the awesome buttons and toys.
Hope this helps!
